# Token Supply Snapshots — Daily Sum Series + Secondary-Measure Weighted Mean

> Token Supply Snapshots — Daily Sum Series + Secondary-Measure Weighted Mean is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-26).

Computes a daily sum time series and a secondary-measure weighted mean for user-supplied token supply snapshot records (circulating_units, total_units), returning two analytical reports.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability token-supply-snapshots-daily-sum-series-secondary-measure-weighted-mean-dd49a150 -d '<json body>'
```

Example prompt: I have token supply snapshot rows with dates, instrument groups, circulating_units, and total_units — can you run the daily sum series and secondary-measure weighted mean reports on them using circulating_units as the primary field? Here are up to 200 rows of data.

## When to prefer this

Use this endpoint when you have pre-collected token supply snapshot data (up to 200 rows) and need both a daily sum time series and a weighted mean computed locally without any external data fetching, live market lookup, or prediction. It is ideal for batch analytical summarization of circulating and total unit data grouped by instrument and date, at very low cost ($0.01 USDC for two reports).

## Known failure modes

- Input array is empty or missing required fields (row_id, date, instrument_group, circulating_units, total_units)
- Date strings not matching YYYY-MM-DD pattern cause validation errors
- More than 200 rows submitted — exceeds maxItems limit
- Numeric values outside ±1,000,000,000,000 range rejected
- Invalid field enum value (must be 'circulating_units' or 'total_units')
- Payment failure or insufficient USDC balance blocks execution

## How this service works

Token supply snapshots — Daily sum series + Secondary-measure weighted mean: Daily sum series + Secondary-measure weighted mean for supplied token supply snapshots records (circulating_units, total_units). Up to 200 rows; 2 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 2 supplied-data reports for up to 200 rows.

## Output

Two analytical reports: (1) a daily sum time series of the selected token supply measure (circulating_units or total_units) aggregated by date, and (2) a secondary-measure weighted mean across the supplied snapshot rows — covering up to 200 input rows.
